A man takes 16 breaths per minute at 18°C
and 760mmHg.What is his rate of breathing
on a mountain-top where the temperature is
-5°C and the pressure is 240mmHg. Assume
that he needs the same mass of air per
minute.

because it is?

DrBESTJC:
I think BiafranDel is correct.....
I got 835Hz which is C

A resonance tube is 40cm long. The tube is three-quarter full. What is the frequency of the turning fork placed near the mouth of the tube? (velocity of sound in air=334m/s) (A) 2511Hz (B) 1670Hz (C) 835Hz (D) 345Hz PLS SHOW YOUR WORKINGS!!

BiafranDel:
okay. Tell the person to send the workings.

BiafranDel:
okay. Post the calculation let me see

BiafranDel:
the full length,L of the tube=40cm=0.4m.

It is 3 quarter filled with water i.e 0.4*3/4= 0.3m which is the length of water.

To find the length of air we say, length of tube - length of water i.e 0.4 - 0.3= 0.1m.

for a closed pipe. fundamental frequency F= velocity/wavelength(4l)

where vel= 334m/s, wavelength= 4L i.e 4*0.1= 0.4m.

Therefore frequency = 334/0.4, frequency= 835hertz. D

DrBESTJC:
This is Smart!........but very technical and time consuming.
And
You will still need a calculator to do it, especially when big numbers are involved.

thanks Eben331

DrBESTJC:
Yes...but the formula I discovered does not give the exact value....only the approximate value..
